Specification of Letters Patent. P-a tented De 13,1921,

Application filed February 28, 1921. Serial No. 448,719.

To all whom it may concern:

Be it known that I, DANIEL D. IIENDER- son. a citizen of the United States, residing at Houston, in the county of Harris and State of Texas, have invented certain new and useful Improvements in Valve-Cleaners, of which the following is a specification.

This invention relates to new and useful improvements in a valve cleaner.

One object of the invention is to provide a device of the character described which is specially adapted for use in cleaning, and removing carbon from, the valve of internal combustion motors, particularly motors used in automobiles.

Another object of the invention is to provide a device of the character described which may be used without removing the valve or in any way disassembling the motor.

A further feature of the invention resides in the provision of a device of the character described which is simple in construction and consequently cheap in manufacture and which is convenient in application and use.

lVith the above and other objects in view the invention has particular relation to certain novel features of construction, opera. tion and arrangement of parts, an example of which is given in this specification and illustrated in the acompanying' drawings wherein Figure 1 is a horizontal sectional view taken on the line 11 of Fig. 2. V

Fig. 2 is a vertical sectional view taken on the line 22 of Fig. 4.

Fig. 3 is an end View, and

Fig. 4. is a plan new of a plunger employed, and

Fig; 5 is a side view thereof.

Referring now more particularly to the drawings, wherein like numerals of reference designate similar parts in each of the figures, the numeral 1 indicates a tubular casing having a lengthwise slot 2 cut through one side thereof, which is in alinement with a corresponding slot 3 cut throughone side of the hollow plunger 4. This plunger is adapted to reciprocate in thecasing and is held against rotation by means of the set screw 5 which is screwed through the easing and whose inner end projects into a groove 6 in the plunger. The casing has a laterally extending tubular handle 7, within which there are bearings in which the crank strokes against 8 works. The upper endof the plunger has a PI'QjjGClZlOIl 9 which extends upwardly therefrom and the inner end of the crank has the spaced pins 10, 10 projecting out therefrom, as shown. Pivoted to the upper end of the casing there is a grip handle'll, one end of which has the depending hooks l2.

In ope-ration, the device is set over the valve stem 13 of any ordinary type of puppet valve motor, said stem projecting up into the plunger 4 and the hooks 12 are engaged over the rocker arm bearing 14: or any other sultable available anchor, said rocker arm working through the slots 2 and 3. The grip handle 11 is then grasped and held firmly against the handle 7 and this will anchor the device firmly in place. The crank 8 is then turned and the pins will alternately engage against the projection 9 and force the plunger 4 downwardly, compressing the valve spring 15.- When the pin passes said projection 9 the spring l5 will suddenly close the valve. The crank is rotated very rapidly, the pins operating as described to open the valve and then suddenly release the same for a quickclosing.

The valve is thus successively opened and suddenly released to permit its quick closing. Carbon and other deposits will there- I by be jarred loose and worn away and thus removed from the valve and seat so as to 7 permit the valve thereafter to .VVhat I claim is 1. In combination, a tubular casing. a plunger adapted to reciprocate therein, a

seat perfectly.

crank rotatably mounted in suitable bearings and means carried bythe crank and arranged to contact with said plunger successively as the crank is rotated.

2. In combination, a casing adapted to it over valve stem, aplunger therein and a rotatable -member adapted to suc essively engage against and release said plunger, whereby the plunger is driven by succe s ve the valve stem to openithe valve. i i

3. In combination, a casing adapted to fit to. permit its quick closing.

at. In combination, a casing adapted to fit over a valve stem, means for anchoring the casing securely in place, a plunger adapted" to reciprocate within the casing, said casing and plunger having allned slots to receive the rocker arm which actuates the valve, a

projection carried by said plunger and a rotatable member provided with actuating means which successively contact with and release said projection as said member is rotated, whereby the valve is opened and released in quick succession.

5.In'co1nbination, a casing, a plunger adapted to reciprocate therein, means for preventing the rotationof the plunger relative to the casing, and a manually rotatable member formed to contact successively against one end of the plunger as said mema plurality of projections which successively contact with the plunger as the crank is rotated.

7 In combination, a casing, a plunger therein, a lateral tubular handle attached to the casing, a crank working through the handle and whose inner end is formed With a plurality of proj ect-ions which successively contact with the plunger as the crank is rotated, and nieans for anchoring the device securely in position during the operation thereof.

In testimony whereof I have signed my name to this specificationin the presence of two subscribing witnesses.

DANIEL D. HENDERSON.
